building errors
OS: Ubuntu 17.04
Thanks for any help :)
Compilation worked (after commenting out add_subdirectory line for examples), but running into errors with building:

If anyone still wondering, just go into the file and add float() to the variables should get rid of this.
Replace line 56 by this one :
Dtype dist = std::max(margin - (float)sqrt(dist_sq_.cpu_data()[i]), Dtype(0.0));
Dtype dist = std::max(margin - (double)sqrt(dist_sq_.cpu_data()[i]), 0.0);
